MYD14A2.061: Aqua Thermal Anomalies & Fire 8-Day Global 1km

AI-generated Key Takeaways

• MYD14A2 V6.1 provides 8-day fire mask composites at 1km resolution, including fire mask and quality information layers.

• The dataset covers the globe and is derived from the MODIS sensor on the Aqua satellite.

• Data is available from July 4, 2002, to November 24, 2024, and has no restrictions on use, sale, or redistribution.

• Users can explore and analyze this dataset within Google Earth Engine.

• Fire mask pixel values represent confidence levels (low, nominal, high) or other classifications such as cloud, water, and land.
